Hepatotoxicity associated with administration of voriconazole (VRCZ) is a major treatment-related adverse event and in some cases requires discontinuation of therapy. This study aimed to investigate the clinical course and risk factors for VRCZ-induced hepatotoxicity.Demographic and laboratory data were retrieved retrospectively from the medical records of 66 Japanese patients who underwent VRCZ treatment. VRCZ-induced hepatotoxicity was defined as an abnormal increase in liver function tests.VRCZ-induced hepatotoxicity was observed in 30 patients (45%), with 11 (37%) of these patients needing to discontinue the drug. Most of the events were observed within 1 to 2 weeks after the first dose of VRCZ. Of the liver function tests, an abnormal increase in γ-glutamyl transferase tended to occur earlier than changes in the other tests (ie, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, and total bilirubin). Multiple logistic regression analysis showed that the trough concentration of VRCZ was a risk factor for hepatotoxicity (adjusted odds ratio = 2.89, 95%CI 1.49-5.59, P = 0.002). Based on this result, a VRCZ trough concentration < 4 μg/mL was considered to be the target for minimizing the risk of developing hepatotoxicity. After discontinuation of VRCZ in patients who developed hepatotoxicity, every liver enzyme abnormality improved within approximately 1 week.In conclusion, this study shows that VRCZ-induced hepatotoxicity may occur early after the initiation of VRCZ therapy. We therefore recommend appropriate adjustments of the starting dose and frequent liver function tests in patients treated with VRCZ, especially during the first 2 weeks.

Discussed in this paper is the vertical load supporting mechanism of laminated rubber bearings with hollow circular sections. The compressive stiffness of the hollow circular rubber bearings is analytically studied. Key issues discussed in this paper are 1) derivation of the governing equation that determines the compressive stiffness of the device 2) effect of bulk modulus on the compressive stiffness 3) proposition of a simple formula which is close to the rigorous solution. As a result of this analytical study, the compressive stiffness of the rubber bearings is proved to be 20 % smaller than is expected from the commonly used conventional model.

This paper discusses a vibration control performance of damping devices installed in a building structure. The motivation of this study comes from the recognition that we often observe much smaller damping performance than is expected from the pre-analytical study in many application projects. Emphasis is placed on the stiffness increase of the structure that is equipped with those damping devices. The relationship between the damping and stiffness augmentation is analytically obtained and expressed in a closed form solution. Therefore, the performance in terms of damping factor is easily evaluated by means of real eigen-value analysis. Numerical simulation is also conducted to ascertain the validity of the proposed method for a relatively large structure under earthquake disturbances.
